What is a major concern when applying pesticides near water bodies?

When applying pesticides near water bodies, a major concern is the potential contamination of water resources. Pesticides can easily run off into nearby water bodies during application or rainfall, which poses significant risks to aquatic life and ecosystems. Contaminated water can affect not only the organisms living in or around the water but also drinking water supplies and the overall health of the surrounding environment. It is crucial for aerial applicators to implement best management practices to minimize any risk to these sensitive areas and to comply with relevant environmental regulations. Ensuring that pesticides do not reach these water resources protects both biodiversity and human health, making this concern paramount in the field of aerial application.
